ha! it's (almost) done (443 files are handled). I will do the merge of
the forrest documentation next week (again, please don't update docs in
HEAD till the merge is completed).
After update CVS HEAD, the OJB-test-suite should give you this result
when running against hsql:
junit-no-compile-no-prepare:

There are many open tasks to handle. I will post some notes in the next
days.
Now we can start with the 1.1 road map in JIRA.
*Andrew*
Could you check the proxy handling in 1.1 (I don't made any changes, but
maybe I corrupt a class). To add the TwoLevelCache proxy-all-references
feature from 1.0.x you only have to modify method
CachingStrategyTwoLevelImpl#materializeFullObject
and to add a custom property like 'strategy.forceProxies'
*Martin*
Could you check the merged ConnectionFactory/connection
pooling/fetchSize stuff.
*Performance profiling*
Compare with 1.0.x branch the HEAD show a performance impact when using
hsql. In 1.0.x the difference between jdbc and PB-api is about 25%
(that's very good) in HEAD it's about 200%

when using DBCP to pool connections with enabled statement pooling the
difference will be reduced to 76% (seems hsql 1.7.5 doesn't support
statement pooling by default).

Anyway this difference is too much, so we should profiling OJB HEAD to
find the hot spots.

Armin
